Description
Technical field
The present invention relates to a kind of large document transmission system and method, relate in particular to a kind of large document transmission system of enterprise network and method of concentrated authorization set management.
Background technology
Along with the fast development of information technology, IT application in enterprises application deepens constantly, need the data volume of transmission increasing, various large-data documents must be realized Internet Transmission fast, and intranet user often feels that the problem of headache comprises following three aspects:
1. big accessory transmission rate is uncontrollable, and large-data documents is transmitted as and ensures that reliability adopts Transmission Control Protocol transmission in transport layer, but is subject to the impact of Transmission Control Protocol congestion control mechanism, and transmission rate can not be controlled, and cannot ensure the file speedy delivery of high priority;
2. large file transfer and Business Processing close coupling, in the time that operation system need to be transmitted large file, operation system needs just can proceed work after pending file end of transmission, and file transfer required time is longer greatly, causes the wasting of resources, operating efficiency low;
3. be difficult to realize breakpoint transmission, when running into the situation that meshed network shakiness or power-off or main frame are restarted in mass data document transmission process, interrupt file transfer, traditional large-data documents transmission can not realize breakpoint transmission, from the beginning transfer files, causes bandwidth resources waste.
For meeting the file of the transmission big data quantity that intranet user is safe, controlled, be badly in need of a safe and reliable big accessory transmission technology.
Summary of the invention
Object of the present invention is exactly in order to address the above problem, and a kind of large document transmission system of enterprise network and method of concentrated authorization set management is provided, and it has advantages of, and speed is controlled, breakpoint transmission, transfer of data and Business Processing decoupling zero.
To achieve these goals, the present invention adopts following technical scheme:
The large document transmission system of enterprise network of concentrated authorization set management, it comprises client, business system server and big accessory server, and client is connected with business system server, and business system server is connected with big accessory server; Described client refers to client personal computer host computer system, has Internet-browser in system.
Described business system server refers to that IT application in enterprises application needs the system of disposing, comprise content management server, office mail server, video server and synergetic office work server, service server includes separate document transmission module and business function module.
Described big accessory server comprises database module, data memory module and transmission control module.
The transmission method of the large document transmission system of enterprise network based on concentrating authorization set to manage, concrete steps are:
Step 1: adopt single-sign-on mode to use licensing to client in the authority set of operation system, complete and once login the mandate that multiservice system uses;
Step 2: access service system server, business system server detects needs the file of transmission whether to be greater than set point; If not upload according to common; If the step 3 of proceeding to;
Step 3: big accessory server is received after transmission request, the round-trip delay of its transmission control module probe transmission, divide block size based on round-trip delay and transmission rate upper limit calculation document, and file block standard is sent to the originating end of large file transfer, originating end is divided into blocks of files when large file being utilized to file set compression cutting techniques by large compressing file according to file block standard, and marks blocks of files and do not transmit;
Step 4: transmit according to the order of sequence the not blocks of files of transmission every the interval of a round-trip delay, often send a data block mark data block for transmitting; If certain time point task is suspended or accidental interruption in transmitting procedure, proceed to step 5; When after All Files piece end of transmission, proceed to step 6;
Step 5: record transmission suspends the breakpoint information that position produces, and in the time that a uncompleted upper subtask starts again, proceeds to step 4;
Step 6: if receiving terminal big accessory server, All Files piece is merged on the memory space being stored under data memory module, and store in the database table of database module according to the database storage mode of definition, otherwise receiving terminal directly merges decompress(ion).
The method that described transmission control module is surveyed round-trip delay is: transmission control module is averaged by sending after ping order obtains round-trip delay.
The described transmission rate upper limit is the transmission rate upper limit of setting according to the significance level of file, the post that participates in transmission personnel and network bandwidth situation, and the transmission rate upper limit is stored in the transmission control module of big accessory server after setting.
Described file block size account form is:
wherein a is TCP transmission initial window size, and MTU is message size, and T is the transmission rate upper limit, and RTT is round-trip delay.
Described database storage mode is: by the attribute of file and memory location, storage format, according to the specification of standard, classification is saved in database.
Beneficial effect of the present invention:
1. can effectively control flexibly big accessory transmission rate, ensure the file speedy delivery of high priority, affected by TCP congestion control mechanism little, transmission rate is stable.
2. document transmission module separates with business function module, can concurrent working when large file when transmission, and improve greatly office efficiency, solve the office hours.
3. there is the function of breakpoint transmission, the maximum using network bandwidth.
